COMB.

PECIFICATION forming part of Letters Patent No. 718,054, dated January6, 1903.

Application filed January 13, 1902. Serial No. 89,505. (No model.)

To a/ZZ wil/01u t may concern.-

Be it known that I, JAMES EWART HEAD, a citizen of theUnitedStates,residin g at the city of St. Louis, State of Missouri, haveinvented a certain new and useful Improvement in Combs, of which thefollowing is a full, clear, and exact description, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, forming' part ofthis specification, in which- Figure l is a side elevational view of myimproved comb. Fig. 2 is an end elevational view of the same. Fig. 3 isan enlarged longitudinal'sectional view of the comb. Fig. 4 is asectional view on line 4 4, Fig. 3. Fig. 5 is a longitudinal sectionalview of a modied form of comb; and Fig. 6 isa side elevational viewshowing one end of the comb in longitudinal section, said viewillustrating another modified form of my invention.

This invention relates to a new and useful improvement in combs, theobject being to provide means in the back of the comb for heating same,the radiated heat raising the temperature of the teeth of the comb,whereby wet hair may be quickly dried.

Another object of my invention is to provide means for generating ablast of air, said blast emanating from the comb-teeth and carrying offmoisture from the hair to be dried. In my preferred construction eachcombtooth is formed with a duct or passage, so that the blast of air isdirected outwardly from the point of the tooth, and in this manner thescalp and the roots of the hair may be quickly dried.

Another object of my invention is to provide a receptacle on the comb,said receptacle being designed to contain perfume or a medicinal fluid,which is carried by the blast of air and directed into and through thehair or onto the scalp. By the presence of a heatgenerating medium inthe distributing airchamber the air forced into and through the hair maybe heated or, if desired, the heatgenerating medium may be renderedinoperative and the air employed at normal atmospheric temperature.

In the drawings, 1 indicates a handle, which is preferably formed withan opening therethrough for receiving supply and return wires of anelectric circuit. This handle carries a hollow ferrule on one end,`whoseshank portion is perforated for the passage of the electric wires.

3 indicates a stem or core extending outwardly from the ferrule, fromwhich stem is arranged a heating-coil 5 in the circuit. Thisheating-coil may be of usual construction.

6 indicates a cap on the end of the stem, which cap engages and holds inposition a housing in the form of a cylinder 7, the edges of saidcylinder being bent outwardlyin parallel lines and clamping between themthe tooth-plate 8. Each tooth (or as many teeth as may be desired) isformed with a duct or passage 9 extending longitudinally therethroughand opening into the chamber formed by the housing 7. This chamber,which will be designated as lO, communicates with the passages l1through the ferrule and with a bore l2 in the handle, to which bore isconnected a iiexible pipe 13, leading to a bellows 14 or some othersuitable sourceofcompressedair supply.

15 indicates a receptacle having an opening communicating with one ofthe passages 11, said opening being controlled, preferably,by aneedle-valve 16. This receptacle is designed to contain liquid ofdesirable character, and in order to insure its discharge into thepassage 1l a pipe communicating at some point with a pressure-chamberleads to the upper end of the receptacle l5 in order that the pressuremay be exerted above Ithe level of the liquid. By regulating a needlevalve the amount of liquid admitted to the air-passage may becontrolled.

In operation the wires from the heating-coil preferably terminate in alamp-socket which when in position in the proper circuit will energizesaid heating-coil, raising the temperature of said heating-coil to adesired degree. I have found that 125 Fahrenheit is sufficient; but thetemperature of the heating-coil may be increased or diminished accordingto circumstances and to special requirements in well-known ways. Indrying the hair the comb is manipulated as usual, and if it is desiredto utilize the blast of air to facilitate the evaporation and carryingoff of the moisture in the hair the bellows or other medium ofcompressed-air supply may be operated so IOO that the air will beemitted in the form of blasts from the ends of the comb teeth. When theheating-coil is in operation, it is obvious that the air becomes heated,and in this heated condition contacts with the hair to be dried. Whereit is desired to use the liquid in the receptacle, the needle-valve isregulated to permit the liquid to flowinto the air-passage with whichthe receptacle is in communication, said liquid being caught up by themoving air and carried to and through the comb-teeth. The handle of thecomb is preferably made of non-heat-conducting material for obviousreasons.

In Fig. 5 I have shown a construction wherein a rubber bulb 18 isemployed upon the core which forms the handle. By this construction thebellows and flexible tubing therefrom to the handle is dispensed withand the airpressure developed locally with respect to the comb.

In Fig. 6 I have shown a construction wherein the comb-teeth are solid.In this form no air-blasts are intended to be used, no provision beingmade therefor.

I am aware that many minor changes in the construction, arrangement, andcombination of the several parts of my device can be made andsubstituted for those herein shown and described without in the leastdeparting from the nature and principle of my invention.

Having thus described my invention, what I claim, and desire to secureby Letters Patent of the United States, is-

1. A comb having a hollow back, the combination with an electric heaterarranged therein but not entirely filling the space in said hollow back,of asupply-pipe for air uuder pressure which communicates with saidspace in the back of the comb, a handle on said supply-pipe and alsoprovided with a passage for compressed air, and wires carried by saidhandle, said wires leading to and from the heating medium in the back ofthe comb; substantially as described.

2. A comb having a hollow back, in combination with an electricheating-coil arranged therein but not entirely Iilling the space in saidhollow back, a supply-pipe for air under pressure which communicateswith said space in the back of the comb, teeth formed with ducts orpassages which also communicate with the space in the back of the comb,a handle formed with a passage for compressed air, said handle alsosupporting the wires which lead to and from the heating-coil;substantially as described.

3. A comb having a hollow back and whose teeth are formed with ducts orpassages communicating with the space in the back of the comb, incombination with a handle, and a duct through the handle for supplyingthe space in the back of the comb with air under pressure; substantiallyas described.

4. The herein-described comb comprising a handle, a cylinder arranged onsaid handle, said cylinder being provided with separatedoutwardly-extending parallel flanges, a toothplate arranged between saidianges and screw-bolts for clamping the flanges on the tooth-plate;substantially as described.

5. The herein-described comb comprising a handle, a-ferrule on thehandle, a core or stem extending from said ferrule, an electricheating-coil arranged on said stem, a cylinder for housing said coil,said cylinder being formed with an elongated opening in one side, andacomb-plate fitted in said opening; substantially as described.

6. The herein-described comb, the same consisting of a handle, a stemmounted upon said handle, an electric heating-coil arranged on saidstem, a cylinder embracing said coil, and provided with anges at itsedges, a comb-plate clamped between said fianges, the teeth in saidcomb-plate being bored longitudinally, and a cap-plate on the end of thestem for supporting the outer end of the cylinder; substantially asdescribed.

In testimony whereof I hereunto affix my signature, in the presence oftwo witnesses, this 8th day of October, 1901.
